To ALL WHOM IT MAY QONGERN:

Be it known that I, A. H. RENNIE, of Binghamton, in the county of Broome, and State of NewYork, have inventeda new and useful Improvementin Shears; and do hereby declare that the following is a full, cl'ear, and exact description thereof', which will enable others skilled'in the artv to make and use the same, reference being had tothe accornpanyingY drawings, forming part of this specification.

The'object of this invention is to construct scissorsor shears in such aA manner that the bladcswill be selfmoving, notrequiring to be operated by the hands. i

Theinveption consists of on'e'rorj'rnbre wheels, attached to one of the blades, and connected with the other blade by crank-motion, so that when the handle of the immovable blade is grasped, and the Wheel or wheels are placed on the counter, andthe shears then moved fbrwardin any desired direction, the other blade will beset in motion by the revolution of the wheel or wheels, and will cut cloth or paper' as quick as the device -is moved forward. I

This machine will prove of special value for tailors and in dry-goods establishments, and lalso for'trimming paper-hangings, but it may be used with advantage for all the purposes for which shearsor scissors are now used.

In the annexed drawing, which represents a side viewiof Vmy improved shears, my invention-is illustrated.

A represen-ts the fixed blade, o n which one or more arms, area.`rranged,to each of which a wheel, b, is secured` which will-revolve freely, when the device is'set on a table, in the manner shown in the drawing. To the wheel b is 'either directly secured a crank, c, or the wheel bis provided with internal gear, as shown, and a pinion, d, is revolved by' the internal gear, the said pinion being also hung on the arm a. The crank c isthen secured eccentrically on the pinion @Las show-n', and its upper end is .connected with the shank of' the cuttingblade B.

A handle, C, is arranged on the shank of blade A, and by it the deviceis handled. It is obvious that, by` moving it forward, the wheel I1 being on the/table or counter, the blade B will receive oscillating motion, and will cut as fast as the-device is moved along. i Y

For better adhesion, and also for protecting thesurface onzwhich the wheel runs, the circumferenc'eoi` the latter may be lined with rubber, if desired. l

Having thus described my invention, I claim as new, and desire to secure by Letters Patent, as a new article of manufacture- -The combination of the blades A B, handle C, arms a, wheelib,'crank. c, and pinion a7, substantially as described, for the purpose specified.
